'System.Dynamic.ExpandoObject' does not contain a property with the name 'Name'

Here is what I have:

var listAddresses = GetAddresses().ToList();
return Json(new JsonResult { Data = new SelectList(listAddresses, "Name", "Id") }, JsonRequestBehavior.AllowGet);

But I get the error 'System.Dynamic.ExpandoObject' does not contain a property with the name 'Name'.

listAddresses is consisted of 10 items. When I debug, when I watch each one of them, I go to Dynamic View and there is Name and Id. How to recolve this?

Solution 
  • var listAddresses = GetAddresses().ToList();
var data = new 
{ 
    Data = new SelectList(listAddresses, "Name", "Id") 
};
return Json(data, JsonRequestBehavior.AllowGet);

    Json(...) is a JsonResult, you don't need both.
